After w3c/fxtf-drafts at bd9fb9b, we need to update our contain
implementation to follow this new behavior. This involves replacing the old implementation
in RayPathOperation::lengthForContainPath to the new behavior, which just bases the length
we shorten the computed path length on half the width or height of the element that we are
animating. Since we no longer need the anchor point or the angle of the ray, remove this
from RayPathOperation::lengthForContainPath's function parameters (as well as all other
PathOperations).
